Self-Employed Dog Groomer
Tax Guide 2026/27

Dog grooming sits in an unusual tax position: it is a service business with a surprisingly capital-heavy startup, a vehicle question that splits the trade neatly in two, and a steady stream of consumable spending that most groomers never bother to record. Whether you rent a chair in someone else's salon, run your own high-street shop, or have converted a van into a mobile grooming unit, your tax bill is driven less by what you charge and more by how diligently you capture the costs of running the business.

How Tax Works for a Self-Employed Dog Groomer

As a sole trader, you pay Income Tax on your profit, not your turnover. Profit is your total grooming income minus your allowable business expenses. For 2026/27 the personal allowance is £12,570, so your first £12,570 of profit is tax-free. Above that you pay 20% up to £50,270, then 40% up to £125,140, and 45% beyond. On top of Income Tax you pay Class 4 National Insurance at 6% on profit between £12,570 and £50,270, then 2% above that.

You report all of this through Self Assessment, with the online filing and payment deadline of 31 January following the end of the tax year (which runs to 5 April). Class 2 NIC has been effectively abolished for most sole traders from April 2024, though paying it voluntarily can still protect your State Pension record if your profit is very low.

If you also have a PAYE job alongside grooming, your tax code controls how much tax is collected on the employed side. Use TapTax's tax code checker to confirm your code before you file; an emergency or out-of-date code can mean you have already over- or under-paid through PAYE, which changes what you owe on the grooming side.

Allowable Expenses for Dog Groomers

The test for every cost is the same: it must be incurred wholly and exclusively for the business. Grooming is one of the better trades for deductions because so much of the spending is unambiguously professional.

A note on training: HMRC distinguishes between maintaining an existing skill (allowable) and acquiring a brand-new one (not allowable, treated as capital). A working groomer attending a CPD day on hand-stripping can claim it; someone taking their very first City and Guilds dog-grooming course before they have a business usually cannot.

The Mobile Groomer Vehicle Question

This is the single biggest decision for a mobile groomer. You have two mutually exclusive ways to claim your van.

The simplified mileage method pays a flat 45p per business mile for the first 10,000 miles in the year, then 25p, and that rate is deemed to cover fuel, servicing, insurance and depreciation. It is simple and needs only a mileage log. Use TapTax's mileage calculator to value it; a mobile groomer covering 12,000 business miles claims £5,000 (10,000 at 45p plus 2,000 at 25p).

The actual-cost method claims the business proportion of every real running cost (fuel, insurance, repairs, road tax, MOT) plus capital allowances on the vehicle's value. For a heavily kitted grooming van that does high mileage and cost a lot to fit out, actual costs can beat the flat rate, but the record-keeping is heavier. You must pick one method per vehicle and stick with it for as long as you own that vehicle. Crucially, the van conversion equipment (bath, table, dryer, generator) is claimed separately as business equipment under the AIA, regardless of which vehicle method you choose.

VAT: When It Starts to Matter

Dog grooming is a standard-rated service, meaning VAT applies at 20% once you are registered. Registration becomes compulsory only when your taxable turnover exceeds £90,000 in any rolling 12-month period. A solo groomer rarely reaches this, but a salon employing two or three groomers, or an operator running several mobile vans, realistically can. The sting is that your clients are pet owners who cannot reclaim VAT, so registration effectively forces a 20% price rise or a 20% cut to your own margin. Monitor your rolling turnover monthly as you grow, because you must register within 30 days of crossing the threshold, and watch out for the Flat Rate Scheme, which can simplify VAT for smaller registered businesses.

CIS Does Not Apply

The Construction Industry Scheme deducts tax at source from sub-contractors in the building trade. Dog grooming is not construction, so CIS never touches you. You receive the full amount your clients pay and settle all your tax through Self Assessment. If a commercial client (say a kennel or a pet shop you groom for) ever suggests deducting CIS, that is simply incorrect.

Scottish and Welsh Groomers

Income Tax on self-employment profit is devolved to Scotland. A Scottish taxpayer pays at the Scottish bands, which for 2026/27 run across six rates: a 19% starter rate, a 20% basic rate, a 21% intermediate rate, a 42% higher rate, a 45% advanced rate and a 48% top rate, applied to progressively higher slices of profit above the £12,570 personal allowance. Your tax code will carry an S prefix. Welsh taxpayers carry a C prefix; Wales can set its own rates but currently matches the rest of the UK. National Insurance and the personal allowance are UK-wide.

Worked Example: A Mobile Groomer on £32,000 Turnover

Priya runs a mobile grooming van, grooming around six dogs a day, four days a week. Her annual turnover is £32,000. In her first year she fitted out the van and bought a full equipment set.

Priya's allowable expenses:

Profit: £32,000 minus £12,280 = £19,720

After the £12,570 personal allowance, taxable profit is £7,150. Income Tax at 20% is £1,430, and Class 4 NIC at 6% on the same slice is £429, for a total of roughly £1,859 in year one. The year-one bill is unusually low because the van fit-out is a one-off deduction; in later years the equipment cost falls away and the bill rises.

MTD for Income Tax: What Changes and When

Making Tax Digital for Income Tax (MTD for ITSA) replaces the annual paper-style return with digital record-keeping and quarterly updates. From April 2026, any self-employed groomer with income over £50,000 must use HMRC-compatible software to keep digital records and submit four quarterly updates plus a final declaration. The threshold drops to £30,000 from April 2027 and is planned to reach £20,000 from April 2028.

A single-chair groomer may stay below £30,000, but a busy mobile operator or a small salon will pass it, and remember HMRC looks at your combined self-employment income if you have more than one trade. TapTax's plain-English MTD guide for sole traders walks through the quarterly process, which software qualifies, and what the deadlines mean day to day. Even below the threshold, photographing receipts as they happen and logging takings weekly makes the eventual switch painless.

Common Mistakes Dog Groomers Make

Capitalising what could be claimed now. Many groomers, on an accountant's old advice, depreciate their equipment over several years. For a sole trader the AIA almost always lets you deduct the full cost immediately, which is more valuable when you are starting out.

Mixing the two vehicle methods. You cannot claim 45p-per-mile and also claim fuel and servicing for the same van. Pick one method per vehicle. The van's fitted grooming equipment is the exception and is claimed separately.

Losing consumable receipts. A weekly wholesaler order of shampoo, blades and bandanas is a few hundred pounds a year that vanishes if the receipts are not kept. Photograph each one.

Under-recording cash and tips. Cash payments and tips are taxable income. HMRC's Connect system cross-references bank deposits and card-processor data, so under-declaring is high-risk and treated as evasion.

Claiming an initial qualification. The cost of becoming a groomer in the first place is generally not allowable; ongoing CPD that maintains your existing skills is.
